#maritime navigation
- Trade wind — A regular and permanent planetary wind that blows throughout the year in intertropical zones, from subtropical high-pressure cells toward the equatorial low-pressure doldrums. Due to the Coriolis force, the trade winds are deflected westward, blowing from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, playing a crucial role in establishing historical maritime routes and regulating global climate.
- Cable length — A traditional unit of measurement for short distances used in maritime navigation, representing the length of a standard towing or mooring cable. Its structural value is equal to one-tenth of a nautical mile, internationally standardized at exactly 185.2 meters or, in the Anglo-Saxon system, approximately 100 fathoms.
- Azimuth — The horizontal angle measured clockwise (from 0° to 360°) between the North direction of a reference meridian and the direction toward a given point on the Earth's surface or the projection of a celestial body on the horizon.
